We just got started on a foundry for casting aluminum parts. I can not find anything worthy made from extruded stock in aluminum so we have to make a casting for the CNC machine.
I'll be making the casting for whoever wants one by the time we finish this project. Here's some photos of the ground work being done.
Over a ton of sand for the foundation. 500# of Sugar Sand #85 mesh for making the green sand and #100 of Bentonite Clay. 70# of Fireclay 4 cubic feet of Perlite and some Diatomatious Earth for parting dust.
I am glad you are doing this. The urge to mess around with melted aluminum has been creeping up on me for a couple years. I have successfully avoided it. ;)
The cast aluminum path is probably the cheapest way to approach this project.
Melt on Monroe!
Cool stuff Monroe.
Now, why an aluminum frame, rather than cast iron?
